Hello all

After the last week, OpenGL has stopped showing the 3D canvas in Windows.
You can reproduce it running reference/OpenGL
The problem disappears by recovering the deleted code in CtrlCore/Win32Wnd.cpp, method Ctrl::InitWin32(), line 261, code beginning with:

	ILOG("RegisterClassA");
	WNDCLASS  wc;
	Zero(wc);
	wc.style         = CS_DBLCLKS|CS_HREDRAW|CS_VREDRAW;
	wc.lpfnWndProc   = (WNDPROC)Ctrl::WndProc;
...

Best regards
Iñaki
